+# Git module
+
+[git](https://git-scm.com/) - a distributed version control system
+
+## What's in this module
+
+[[_TOC_]]
+
+## Global git settings
+
+This is probably the first thing that needs to be customized, since it points to a different identity for each git user.
+
+## Basic git command aliases
+
+This module contains a heap of aliases to every-day git commands.
+Most of them follow a two-to-three letter combination of things to do which corresponds to the mnemonic of the longer git command.
+As such, they are mostly similar to those found in the Oh My Zsh [git plugin](https://github.com/ohmyzsh/ohmyzsh/tree/master/plugins/git)
+Examples of some common aliases are `alias ga=git add`, `alias gst=git status`, `alias gp=git push`, `alias gl=git pull`.
+
+## Gitignore generation script
+
+Adds a `gitignore` script which pulls relevant .gitignore lines from [gitignore.io](https://www.gitignore.io) and sends them to standard out, or creates a .gitignore file in the current directory.
+
+[![asciicast](https://asciinema.org/a/298616.svg)](https://asciinema.org/a/298616)
+
+To show usage of the script run `gitignore -h`. It is fully equipped with zsh auto completions, which will pull a list of all available ignore modules from the website to complete with.
+
+It can alternatively be run through git itself by invoking `git ignore`, which will always generate a .gitignore file in the current directory.
+
+When fzf is installed invoke the script without any arguments to generate a fzf-searchable list of git definitions to create. Select multiple definitions with <tab>.
